WINDOW-LOCK.

T 0 all whom it may concern:

Be it known that'I, ANSON E.-CLAY, a citizen of the United States, residing at Newton, inthe county of Jasper and State of Iowa, have invented a new and useful Window-Lock, of which the following is a specification.

This invention relates to improvements in window locks, the object of the invention being to provide an improved device of thischaracter by means of which the sashes of a window may be opened for some distance so as to permitwentilation and are so looked that it will be impossible for any one on the outside to open the window sufficiently to permit entrance into the room.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention consists in the novel features of construction and combination of parts which will be more fully described hereinafter and particularly pointed out in the claim.

In the drawings accompanying and forming part of this specification,

Figure 1 is a fragmentary sectional elevation of apair of window sashes illustrating my improved lock applied thereto;

Fig. 2 is a front view of the locking device applied to the upper and lower sashes of a window, the frame of the sashes being broken away;

Figs. 3, 4 and 5 are respectively a front elevation, a side elevation and a bottom plan view of the member of the device adapted to be secured to the upper sash;

Fig. 6 is an end view of the member of the device which is adapted to be secured to the lower sash;

Fig. 7 is a longitudinal section thereof;

Fig. 8 is a section taken on the line 8-8 of Fig. 7, looking in the direction of the arrows; and

Figs. 9, 10 and 11 are respectively an end view, a plan view and a side view of the locking bolt adapted to cooperate with the upper member for locking the window in open position.

The same characters of reference designate the same parts in the different figures of the drawings.

Referring to the drawings, 2 designates the lower frame member of the upper sash and 3 the upper frame member of the lower sash. My improved fastener or look com- Specification of Letters Patent.

prises a socket member 4, which may be struck up from a single piece of sheet metal. This socket member is adapted to be secured by meansof screws passing through perforations 5 formed in the base portion thereof. The member 4 is open at the front, as shown in Fig. 3, the side walls of this opening being dovetailed as shown at 6 in Fig. 5, except for a short distance from its lower end, where the side walls of the opening are cut away as shown at 7 to provide straight side walls, the opening at this point being of a width equal to the wider rear portion of the dovetailed opening. -A bar 8 extends across this wider opening for a purpose to be hereinafter described.

A chambered member 9 is adapted to be secured to the upper frame -of the lower sash, this member being provided with a pair of perforated cars 10 for the passage of screws. The front portion of this member is provided with a chamber having tapered side walls, as shown in Fig. 8, merging into a rear sleeve portion 11 having a straight bore. Within this chambered member is adapted to operate a locking bolt or plunger provided with a head 12 having tapered side walls, as shown in Fig. 10, this head being adapted to be normally seated within the front chamber of the member 9, while the stem or shank 13 thereof extends through the sleeve portion 11 and is provided outside of such sleeve with an operating knob or handle 14. A coil spring 15 is housed within the sleeve and encircles the shank 13 and presses against the head 12 of the bolt to normally protract the same from the chambered member 9.

The operation of the device is as follows: The socket member 4, as stated, is secured on the lower frame of the upper sash and the chambered member 9, with the bolt housed therein, is secured to the upper frame of the lower sash. When it is desired to lock the window in tightly closed position the bolt is permitted to extend into the socket below the bar 8, and it will be readily seen that in this position it will be impossible to push the lower sash up or pull the upper one down. When, however, it is desired to leave a portion of the window open for ventilation, the bolt is withdrawn from its position in the socket below the bar 8 and the lower sash moved upward until the bolt is opposite the opening 7 above the bar, whereupon the operating handle or knob is released and the bolt allowed to enter the socket under the tension of its spring. The Window may then be opened either from the top or bottom, or both, to the extent of the length of the socket 4:. While I do not de- 7 sire to confine my invention to any particu-, lar length, it will be understood that the invention is intended to permit the window'to be opened sufficiently to ventilate the room without making an opening large enough to permit a personto enter the room through the open window, and therefore it is believed the most practical length for the socket is about five inches. From the construction de scribed it will be observed that it would be impossible for any one to reach in and withdraw the bolt from the socket, since the only place that such withdrawal can take place is when the bolt, is opposite the opening 7, and therefore the window is so nearly closed that there would not be sufiicient room to permit a persons hand or a tool of any kind to be used for withdrawing the bolt.

While I have described in detail the structure herein illustrated, it is to be understood that I do not thereby limit my invention to the precise features ofconstruction shown, as I am aware that manymechanical changes and modifications may be made therein without departing from the, spirit and scope of the invention as set forth in the claim here-. to appended. g

Having-thus described my invention, what I claim is: V

In a device of the class described a member having an elongated socket defined by rearwardly diverging walls and provided at its lower end with an enlarged opening,

the member havingxa cross bar defining the ber on the upper sash of a window, and means :formounting the casing on thelower sash of a window. Q

In'testimony that Iclaim the foregoing as my own, I have hereto afiixedmy signature in the presence :of two witnesses.
